so given the function below if f(x) = -1
find the value of x
f (x) = 4x +11
The value of x is found to be -4.
What is a function?A function y = f(x) is a one to one relation between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
Given function is as below,
f(x) = 4x + 11 (1)
And, f(x) = -1
Substitute the value of f(x) in equation (1) to obtain,
-1 = 4x + 11
=> 4x = -1 - 11
=> x = -12/3
= -4
Hence, the value of x is obtained as x = -4.

Hello there! :)
To find the mode, we must simply find the number that is seen most often in the dataset.
Here, the number 81 is seen twice.
87 is seen once
93 is seen once
89 is seen once
61 is seen once
So 81 is the mode.

A news report says that 9% of middle school students are on the track team.
There are 600 students in your middle school.
How many students in your school would you expect to be on the track team?
Answer:
54
Step-by-step explanation:
1% of 600 is 6 (600/100), so 9% of 600 is 54
Answer:
54 students
Step-by-step explanation:
To calculate 9% of 600 first convert 9% to a decimal. This is done by dividing it by 100.
9% ÷ 100% = 0.09
Multiply 600 by 0.09:
600 × 0.09 = 54
So 54 students at the middle school are on the track team.

There is a line above one of the 5
a) let p,q and r be propositions. Simplify the following compound proposition: ((¬ r)∧p∧q)∨((¬ r)∧(¬ p)∧q).
b) Using two different methods determine whether the propositions (p⟶q)⟶q and p∨q are logically equivalent.
a) Starting with
(¬r ∧ p ∧ q) ∨ (¬r ∧ ¬p ∧ q)
distribute the disjunction (∨) :
((¬r ∧ p ∧ q) ∨ ¬r) ∧ ((¬r ∧ p ∧ q) ∨ ¬p) ∧ ((¬r ∧ p ∧ q) ∨ q)
and once more among the grouped statements:
(¬r ∧ p ∧ q) ∨ ¬r ≡ (¬r ∨ ¬r) ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)
(¬r ∧ p ∧ q) ∨ ¬p ≡ (¬r ∨ ¬p) ∧ (p ∨ ¬p) ∧ (q ∨ ¬p)
(¬r ∧ p ∧ q) ∨ ¬p ≡ (¬r ∨ q) ∧ (p ∨ q) ∧ (q ∨ q)
So, the original statement is equivalent to
[(¬r ∨ ¬r) ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)] ∧ [(¬r ∨ ¬p) ∧ (p ∨ ¬p) ∧ (q ∨ ¬p)] ∧ [(¬r ∨ q) ∧ (p ∨ q) ∧ (q ∨ q)]
which reduces to
[¬r ∧ (p ∨ ¬r) ∧ (q ∨ ¬r)] ∧ [(¬r ∨ ¬p) ∧ (q ∨ ¬p)] ∧ [(¬r ∨ q) ∧ (p ∨ q) ∧ q]
and further to
¬r ∧ (p ∨ ¬r) ∧ (¬r ∨ ¬p) ∧ (q ∨ ¬p) ∧ (p ∨ q) ∧ q
For any statements X and Y, we have the identity
• X ≡ (X ∨ Y) ∧ (X ∨ ¬Y)
so another step of simplification reduces the underlined expressions to
¬r ∧ ¬r ∧ q ∧ q
which leaves us with
¬r ∧ q
###
b) Recall the identity,
p ⇒ q ≡ ¬p ∨ q
Then
(p ⇒ q) ⇒ q ≡ (¬p ∨ q) ⇒ q ≡ ¬(¬p ∨ q) ∨ q
Distributing the negation gives
(p ⇒ q) ⇒ q ≡ (p ∧ ¬q) ∨ q
and distributing the disjunction gives
(p ⇒ q) ⇒ q ≡ (p ∨ q) ∧ (¬q ∨ q)
from which it follows that
(p ⇒ q) ⇒ q ≡ p ∨ q
Can I get help with question 6-9
For 6 I’ve already done it I just need assistance and see if I did it correctly
Answer:
Step-by-step explanation:
6)For question 6 you have the right idea but as the new image is bigger than the pre-image the scale factor would be 3/1
7)You have the right answer but the fraction can be simplified to 2
8)I think this question is asking for the angle in the triangle on the left that is the same as the one on the right so from left to right,
F=R G=S H=T
FG=RS GH=ST FH=RT
9)The scale facto for the longest edge here is 2 but the scale factor for the shortest edge is 18/8 which is equal to 9/4 so the are not congruent as they have two different scale factors. Answer) no
10) the triangles are similar as angle a=n and 55+35+90 = 180 so yes they are similar
Hope this helps :)
